Saw the video last night and I had nightmares. Now that you have mentioned this, I may not be able to sleep again. Very scary indeed!

I have to admit, the tech you guys have made this Singaporean's eyes popped out.

I don't think it is scary. There is a place where math becomes art. This is the place - a higher level. There are also individuals in our world who don't want to just compete, they want to dominate and will do what it takes to do that, lining up all the correct resources and talent. It is being showcased here. Strategy is part of the game but that same approach can be used in real world decision-making and in companies and how they run themselves. It's part of the vision that is promoted in FIRST and has culminated in the Robowranglers and what they are capable of.

Pretty cool.

This one is a top contender. Your bot will inspire even those who are not on your team.

Great job!

First off, amazing robot. Ridiculous that yall can pump that out in six weeks. This year we were shooting to make something 1/100th that awesome but unfortunately have thus lost out on a lot of valuable practice time.... :/
Still, compliments to you for such and amazing robot. Crazy....

On the discussion of how their "ball magnet" works, go to 2:28 in the video. As they drive up the hill to push the ball into the goal, the ball is stuck to the robot and hovers. First off, I am pretty sure that it is a roller system, not suction. If the ball isnt rolling and it is a roller system, does that mean the ball is pinched in? Is that really legal, or would that technically be a penalty (because the ball must the tiniest bit off the ground, right???) Is it just designed that the ball is pinched so low to the ground that is barely hovering? Is the roller torqued up so that it basically stalls when the ball is locked in place...? This is the buggiest part of our robot still...

I cant wait to (hopefully) see this thing at atlanta. Luckily, even is we dont make it, I can stop by... Too bad its leaving atlanta next year...

I don't follow. What makes a ball wedged under a roller (if it was) lift off the ground? Say the ball does get wedged in that shot. What is supporting it other than the ground?

I mean to say that the rollers pinch the ball just enough to hold it and squeeze it in...Nothing physically under the ball. Sorry bout my wording.

thats exactly what i was thinking, it looks like an amazing ball dribbler but it looked like the ball was not in contact with the ground when it was gathered but i could be wrong...just my POV

[Nick Lawrence]

Now that, is a robot.

My god is that ever a robot.

That is everything I dreamed of and more, for a championship winning robot.

I want one!

Good question -- after some extra viewing, especially with the side angle from the tunnel, it appears that the tractions are inline with the omnis. If you think about it, having only 4 wheels on the ground with the outer four corners being the contact points would mean the bot couldn't turn exceptionally well. Yet that is a very agile robot. Thus I'd say it's 8 on the floor. It's practically ingenious, and I'm very curious to know how the module are actuated. My initial thoughts would be a spring suspension that's pulled up via rope that's attached to a window motor. The modules pivot cocentric to the omnis, thus the bumper zone planes never change. I think the rope would stretch over time though. Hmm.

Ingenious indeed.

Wow, that IS a sticky ball magnet! Hopefully not too sticky

[dodar]

so that means they are carrying then, right?

[MrForbes]

I don't know, I'm not a referee

[Nick Lawrence]

Uhm, isn't that bad?

-Nick

[dodar]

ya, carrying is illegal
